Good product,....... keep up the good work.

*by J***. on July 2, 2016*

Great for maintaining my very small and lightweight but pricey battery in my Porsche. It is a lot more than a trickle charger. It cycles and conditions the battery. A must have for vehicles that sit or that have lots of electronics running in the background even when powered down.

### ⭐⭐ Charger do not extend battery life as advertised
*by D***N on July 29, 2015*

Bought one unit handy to use when necessary for regular battery maintenance. Charger was bought brand new. When car could not start, set up the unit to charge battery to 13.9 to 14.1Volt for 96 hours; un-plug charger and let battery rest overnight with no load. Reconnect battery terminals, crank starter but it could not start engine, start recharge cycle 2nd time for another 72 hours and it still could not start the engine. Checked battery voltage, it indicated 11.6Volt. Followed all written instructions closely but it could not save battery. Similarly tried charging other SLA battery many times, it did not work either. Batteries were 34 to 50 month. This Granite Digital (GRT999) Save A Battery Charger worked normally - confirmed with digital multimeter. All unserviceable batteries were maintained & charged regularly using this unit but it doesn't really help extend battery useable life. It seems to be just a sales gimmick. Can someone provide pointers ?
